What does “fuel mix” mean?

A supplier’s fuel mix shows the sources of the electricity that it supplies to its customers e.g. coal, gas, nuclear and renewables.

Over the course of a year, energy suppliers must purchase sufficient electricity to feed into the national electricity grid to cover the amount their customers take out. At the end of each year, suppliers must disclose their fuel mix to the electricity and gas regulator, Ofgem. This information is published annually to help consumers make informed choices about their electricity supplier. At Good Energy, we ensure that all the electricity we sell to customers each year is matched 100% with electricity sourced from renewables.

Greenhouse Gas Emissions and nuclear waste

An average unit of electricity in the UK (a kilowatt hour or kWh) results in 360g of carbon dioxide (CO2) emissions and 0.007g of radioactive waste†.

But the electricity we supply contains 0g of CO2 and no radioactive waste.

This will never change.

How do we know it's 100% renewable?

At Good Energy, we generate renewable power from our own wind and solar farms and buy renewable power from small independent renewable generators. Added together, this will match the amount of electricity we supply to our domestic and business customers across the UK.

Good Energy Wind and Solar Farms

Good Energy has developed over 150 megawatts (MW) of renewable energy farms, as part of our continued commitment to 100% renewable energy. We own and operate seven solar farms and two wind farms. Together these sites generate enough electricity to power over 18,000 homes.

New sources of renewable electricity

Renewable power from offshore wind farms has also become part of our energy mix for the very first time as we now source electricity for our customers from Westermost Rough Wind Farm, situated in the North Sea, five miles off the Yorkshire Coast north of Hull. We purchase 12% of the overall output from the 210 MW wind farm. Over the course of a year, that’s enough renewable electricity to supply more than 33,000 average homes.

We are also supporting the proposed Swansea Bay Tidal Lagoon project in South Wales to help bring tidal power to the UK. By investing in the project’s early-stage development, we will be able to purchase 10% of the electricity output when the project is completed – that’s the same amount of electricity generated by our wind and solar farms combined!

Green Gas

We see natural gas as being a necessary transitional fuel, playing an important role in heating and cooking as we move towards the ultimate goal of a 100% renewable future. We are doing all we can to make this transition a reality, so now 6% of our Green Gas comes from biomethane. This is gas produced from organic matter – like manure and sewage – right here in the UK. Biogas is chemically identical to natural gas but can be created and used with less impact on the environment.

To make it totally carbon neutral however, emissions from the gas our customers use will be neutralised through verified carbon-reduction schemes in Vietnam, Nepal and Malawi. Not only do these offset the carbon emissions from the gas we supply, they also bring many economic, social and health benefits to the local communities involved.
